Sleeping late at night could increase risk of type-2 diabetes: Study

The research, which was led by Sina Kianersi at Brigham and Women’s Hospital and Harvard Medical School, had taken a sample size of 63,676 nurses in the age groups of 45 to 62 years. As per the requirement of the study, the researcher chose the samples with no history of cancer, cardiovascular disease or diabetes. The study was conducted from 2009 to 2017. The study included self-reported sleeping habits, diet, weight and BMI along with sleep timing, smoking or drinking behaviour, physical activity and family history of diabetes of the sample population.

Among the participants, 11 percent were reported to have a definite evening chronotype while 35 percent were reported to have a definite morning chronotype. The rest of the participants were labelled as intermediate as they were not considered in either of the chronotypes. However, after accounting for the participants over their day-to-day lifestyle factors, evening chronotypes were found to have a 19 percent higher risk of type 2 diabetes than the early risers, who have better lifestyle habits.

As per the report, the evening chronotype individuals were also found to be more likely to consume alcohol in higher quantities. These participants were found likely to have weight issues, the habit of smoking and fewer sleeping hours.

Apart from Sina Kianersi, the team included Yue Liu, Susan Redline, Eva Schernhammer, Qi Sun and Tianyi Huang who contributed to the study.
